HENRY SEARL, OF ROCHESTER, NEW YORK.

IMPROVEMENT lIN OIL-EJ ECTORS.-

To all whom it may concern Be it known that I, HENRY SEARL, of Rochester, in the county of 'Monroe and State of New York, have invented a new and Improved Pump; and I do hereby declare that the following is a full and exact description thereof.

' The nature of my invention consists'in constructinga pump for deep wells, which pump has a `receiver which takes the place of a workin g-barrel, with a valve at the lower end and a cap at the upper end, anda pipe to eX- 'tend from the top of the well down through .the cap of the receiver, a-nd through which pipe steam is forced into the receiver, and another pipe,which has a valve in the lower end, and which extends from near the bottom of the receiver up through the cap to the top of the well, this pipe to be called a supply-pipe, so that when steam isjforced down through the steam-pipe into the receiver the lower valve is closed by the pressure and the valve in the supply-pipe is opened, and whatever is in the receiver is forced up the supply-pipe and held up by the valve. Then the steam is allowed to blow oif and condense, forming a vacuum, and the water or oil is drawn up in the receiver, and by letting the steam on again whatever is in the receiver is again forced up the supply-pipe, and thereby produces a reciprocating motion without the use of a piston or sucker-rod.

To enable others skilled in the art to make and use' my invention, I will proceed to describe its construction and operation by referring to the annexed drawings and letters of reference marked thereon, in which- Figure 1 represents a section of a well with my pump ready for operation. Fig. 2 is a section at A B, Fig. 1. Fig. 3 is a section at O D, Fig. 1. Fig. 4 shows a section of the lower part of the well with a section of the receii-'ernnd the steam and supply pipes connected with it, and also showing a section of the valve in the lower end of the receiver and in the lower end of the supply-pipe.

E E, Fig. 1, represent a section of the well. F F, Fig. 1, show a section of the seed-bag which is used in oil-wells to pack around the pipes and keep the surface-water from the well. G, Fig.1, shows the receiver of my pump, which may be of any desired length. H, Fig. l, shows the pipe which carries the steam directly from the boiler without-the use of an engi-ne to the receiver. The'steam is admitted tothis pipe at I,- Fig. l'. "J,`Fig. l, shows the supply-pipe up through which the water or oil is forced, and which cornes out at K, Fig. 1. L, Fig.' 1, shows a pipe by means of whichthe steam which is blown ott' in. exhausting the pump is made to escape in the well below the seed-bag for the purpose of helpingwarm the water in the well outside ofthe pump. M, Fig. l, shows a stop-cock which shuts oit'from or lets on the steam to the pump. N, Fig. 1, shows a stop-cock between-the pipes H and L, Fig. 1.

O, Fig. 1, shows a stop-cock by means of which air can be let into the well through the pipe L, Fig. 1, so as to keep an atmospheric pressure on the water or oil, or to let thegas in the well escape. P,Fig. 1,shows a stop-cock which lets the steam from the pipe H blow oil inthe air. Q, Fig. 1, shows a stop-cock by `means of which the steam can be shut olf from the pump if it should be desirable to let the whole force of steam down the well outside of the pump through the pipe L, Fig. 1

F, Fig. 2, shows the top ofthe seed-bag F F, Fig. 1. H, Fig. 2, shows a section of the stram- .pipe H, Fig. 1. J, Fig. 2, shows a section ofthe supply-pipe J, Fig. l. L, Fig. 2, shows a section of the pipe L, Fig. 1.

G, Fig. 3,. shows the top of the receiver G, Fig. 1. H, Fig. 3, shows a section ofthe steampipe H, Fig. l. J, Fig. 3, shows a section of the supply-pipe J, Fig. 1.

E E, Fig. 4, represent a part of a section of the well shown E E, Fig. 1. G G, Fig. 4, show a section of the cap of the receiver G, Fig. 1. R R, Fig. 4, show a section of the cap of the receiver G H, Fig. 4, shows the steam-pipe H, Fig. 1, as it passes through the cap of' the receiver It R, Fig. 4.- J, Fig. 4, shows the supply-pipe J, Fig. 1. S, Fig. 4, shows a section of the valve in the lower end of the supplypipe J. l, Fig. 4, shows asection of the valve in the lower end of the receiver G.

N ow, it will be seen that by opening the cocks M and Q, Fig. and closing the cocks N O and P, and then forcing steam down the pipe H, Fig 1, into the receiver G, Fig. 1, the pressure on the water or oil in the receiver closes the valve T, Fig. 4, and opens thevalve S, Fig. 4, and allows the water or oil to go up the pipe J and out at the top at K, Fig. 1.

G, which in ay be 'Ihe valve S also holds up the water or oil when the pressure is removed.

ltwill also be seen that by closing the cock M and opening the cock N, Fig. 1, the steam is allowed to pass from the pipe H into the pipe L, down through the seed-bag F, into the well outside the pump, and materially assist in warmingI the well, both above and below the. seed-bag, which is desirable, as it warms the water varound thel pipes, and prevents the steam in the pipe II from condensing too much.

1t. will be seen that the pipe L being shorter than the pipe H, the steam will rise in the pipe II, thereby forming a vacuum in the receiver (l, which is immediately filled by the atmosphericpressure,lifting the valve T, Fig. 4, and the water or oil is drawn up into the receiver of any desired length.

Now, by closingthe cock N and opening the cock M the steam is again forced down the pipe II, and the oil or water is again forced np the pipe J, the valves S and T, Fig. 4, operating as before described, thereby producing a reciprocating motion, without the use of a suckerfrod or piston.

The well can also he heated the whole length oi' the pump by letting the steam run down the pipe II and up the pipe-J for any desired length et' time without the. reciprocating moton.

1t will also be seen that by closing the cocks M and N and opening the cock I the steam in the pipe II is allowed to blow oft' in the air, and in that way form a vacuum in the pump, and by 'closing the cock N and opening the cock 0 the air is allowed to pass down the pipe to keep atmospheric pressure on the well.

ltwill also be seen that it` at any time it is desirable to force steam down the well outside ot' the pump Ait can be done by closing Jthe cocks L), I, and 'Q and opening the cocks M and X, thereby forming a direct connection with the boileiI and the pipe L, Iig. l.

The advantages ot' this pump over those z now in use are, first, no engine is required to work the pump; second, the piston or sucker-rod with a valve is not required g third, a finished working-barrel, as used in other force-pumps, is not required, fourth., the Well is heated to a high degree oi temperature, which is very desirable both to hold in solution and melt out theparaiine, and to rarefythe gas and warm the oil so that it rises and pumps more freely, and which would also have a tendency to cause a well to flow; fifth, doing` away with the engine and sucker-rod and finished working barre-l simplifies the pump and makes it more economical than those now in use, both in lirst cost-and in operating.

Having thus tully described the construetion and operation of my improved pump, I would observe that I do not wish to be understood as claiming the use of steam orcompressed air for ejecting oil or other fluids from deep wells, believing,as I do, that the same are in common use; but

rhat I do claim as my invention, and desire to secure by Letters Patent, is

l. The arrangement of the receiving-chamber G in an oil-well or other deep well, when vsaid chamber is connected' with the surface or mouth ot the well by means ot' the, steam! pipe II and t-he @duction-pipe J, and when said receiving-chamber is supplied with the induction-valve T and the eduction-pipe J is supplied with a suitable valve, S', all substantially in the manner and for the purpose herein set forth, but not intending to be nnderstood as making any speeitic claim to the induCtiOnYalVc T in said pumping apparatus. 2. The arrangementot' the cocks M, N, O, i, and Q, in combination withthepipes ILL, and J, all operating in the manner and fur the purpose substantially as herein described and represented.
